Abstract

ABSTRACT Technologies that improve water use efficiency (WUE) and increase crop yields are essential for the development of a responsible and productive agriculture. Therefore, the objective of this study was to evaluate economical planting beds with the use of mulching and application of different irrigation water depths as a water-saving technology, and determine the irrigation water depth that promote the optimal plant development and fruit yield and quality of two cherry tomato cultivars. The experiment was conducted at the Federal Rural University of Pernambuco, Serra Talhada, PE, Brazil. A randomized block experimental design with split-plots (5×2) was used, with plots consisting of five irrigation water depths (25%, 50%, 75%, 100%, and 125% of the crop evapotranspiration - ETc) and subplots consisting of two cherry tomato cultivars (Carolina and Yubi), with four replications, totaling 40 experimental units. The development of tomato plants was evaluated through biometric measurements of stem diameter, plant height, and canopy area. Additionally, the following variables were evaluated during fruit harvest: number of fruits, mean fruit weight, fruit diameter, fruit yield, WUE, titratable acidity, pH, and soluble solids content. The economical planting beds promoted increases in WUE. Irrigation water depths lower than 100% of ETc resulted in better plant development and higher fruit yield, number of fruits, and WUE for the evaluated cherry tomato plants. The cultivar Carolina exhibited higher production performance compared to Yubi.

覆膜经济苗床灌溉圣女果的生产

提高水资源利用效率(WUE)和增加作物产量的技术对于发展负责任的高产农业至关重要。因此，本研究的目的是评价覆盖经济种植床和不同灌溉水深的节水技术，确定促进两个樱桃番茄品种植株发育和果实产量品质的灌溉水深。该实验是在巴西伯南布哥联邦农村大学(Serra Talhada)进行的。采用分块随机区组试验设计(5×2)，分块为5个灌溉深度(作物蒸散量的25%、50%、75%、100%和125%)，分块为2个樱桃番茄品种(卡罗莱纳和育碧)，4个重复，共40个试验单元。通过茎粗、株高和冠层面积等生物计量指标对番茄植株发育进行评价。此外，在果实收获期间评估以下变量:果实数量，平均果实重量，果实直径，果实产量，水分利用效率，可滴定酸度，pH值和可溶性固形物含量。经济的种植床促进了水分利用效率的提高。灌水深度低于100% ETc的樱桃番茄植株发育较好，果实产量、果数和水分利用效率均较高。与玉碧相比，卡罗莱纳表现出更高的生产性能。
